Don Chamber Lid D10123 Rayburn 5" For 8" Conversion

Don Chamber Lid D10123 Rayburn 5" For 8" Conversion

The Don Chamber Lid (Part Number: D10123) is a specialized cast-iron component used in the conversion of oil-fired Rayburn cookers. Specifically, it is designed for use when a 5" Don burner is being adapted or utilized within an 8" burner chamber configuration.

Don burners (vaporizing sleeve burners) were a popular conversion for solid-fuel Rayburns to turn them into oil-fired appliances. This lid ensures that the smaller burner assembly interfaces correctly with the larger chamber, maintaining the airtight seal and heat distribution required for efficient cooking and water heating.

Key Features and Specifications

Part Number: D10123.

Application: Adapts 5" burner components for 8" conversion housings.

Material: Heavy-duty cast iron to withstand the high constant temperatures of a vaporizing oil flame.

Compatibility: Used in vaporizing oil conversions for Rayburn Royal, Regent, and 200 series.

Function: Directs the heat and flame path correctly into the cooker’s flueways while preventing "false air" from entering the combustion zone.

Common Applications

Oil Conversions: Essential for older Rayburns that have been converted from solid fuel to oil using the "Don" vaporizing system.

Burner Servicing: Replaces lids that have become warped, cracked, or "burnt out" due to decades of constant heat exposure.

Restoration: Used when rebuilding a vaporizing burner to ensure the flame remains stable and centered.

Installation and Maintenance

Seal Integrity: The lid must sit perfectly flat. If the edges of the chamber or the lid are pitted, a small amount of high-temperature fire cement or specialized rope seal may be required to prevent air leaks.

Cleaning: During the annual service, the underside of the lid should be scraped clean of any carbon deposits or "soot" to maintain optimal heat transfer.

Inspection: Check for "thinning" of the cast iron. If the lid has become significantly thinner in the center, it is nearing the end of its life and should be replaced to prevent it from cracking and falling into the burner.

Essential Companion Products

Don Burner Sleeves: 5" or 8" perforated stainless steel sleeves.

Wicks: Replacement Kindler Wicks for vaporizing burners.

Oil Control: BM (Toby) or CI oil control valves.

Catalysts: Stainless steel burner catalysts to improve combustion efficiency.
